If you know where Silverton Mountain is, then you know Marmot's designers weren't fooling around with the Silverton Jacket, a solid piece of alpine hard-wear. GORE-TEX®Pro 3-Layer fabric is impervious to wind and water, but never feels clammy. It’s gasket compatible for pro-level layering options, and absolutely packed with big-mountain functionality. Make no mistake; this bad boy is seam-taped, helmet-ready, and too hard to fail.
